The EcoFlow x Shelly Pro 3EM Smart Meter is a slim 62 g DIN-rail device dedicated to three-phase installations. In a 94 x 19 x 69 mm body it reads every phase in real time through three detachable 30 x 30 x 50 mm clamps closed around the live conductors after the main breaker. Voltage, current and power flow into the EcoFlow app over Wi-Fi 802.11 b/g/n or an Ethernet cable, and Bluetooth 4.2 speeds up the initial handshake. The meter itself consumes less than 3 W.

• Three-phase measurement with removable clamps for a clean install in busy cabinets.
• Live voltage, current and power tracking, per-minute values retained for at least 60 days.
• Wired Ethernet or Wi-Fi connection to the app.
• Feeds STREAM home batteries (AC, AC Pro, Max, Pro, Ultra, Ultra X) for self-regulating operation.
• Compatible with wire cross-sections between 0.5 and 2.5 mm².
• Bluetooth 4.2 makes app pairing quick.
